have you (jimbohick) considered this as a way of getting the site more attention? that is to say you put one sites' banner on librarius and they put one on theirs about librarius.
heh...I thought Grand Poobah was the most interesting self-appointed title in my sig Banner exchange IS a good idea, but I personally don't like banner pages, since every banner looks different and none match the site's design. Anyway, I should get back to some programming this weekend hopefully; I've been dreadfully busy.
